Chemistry, Properties & Perfumer Guide
The Chemistry
The essential oil contains aldehydes like decanal and dodecanal alongside monoterpenes. These volatile compounds create its distinctive citrus-herbal character. Extraction typically involves steam distillation of fresh leaves, yielding about 0.2-0.5% oil. The aldehyde content makes it reactive in formulations, requiring careful handling to prevent oxidation.
